Suppose I have a wooden cube, which I then split into eight equal pieces. If I give you two of those pieces, and then give you three more, what fraction of the original cube do I have left? Express your answer in decimal form.
Answer:
.625
Step-by-step explanation:
Since the amount of pieces are 8, and you gave 5 away, you have to divide 5 by 8. This gives you .625
Answer:
0.375
Step-by-step explanation:
You would have 3/8 of the original cube left. 0.375 in decimal form.

Which expressions are equivalent to -3(2+7) A: -6+21 or B:-21+6
Answer:
None
Explanation:
-3(2+7) = -3×9 = -27

The first blank is for your m, the last blank is your b(write fractions as = 1/2)
PLEASE ANSWER NOWWWWWWWWW
Answer:
m = -4/3 b = 0
Step-by-step explanation:
Slope formula is [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
[tex]\frac{-4-0=-4}{3-0=3}[/tex]
The slope is -4/3. The line intersects the y-axis at (0 , 0) so b = 0. This can be verified by plugging one of the points into the equation.

Consider two consecutive odd positive integers. If their product is 23 more than their sum, what
are the two integers?
Answer:
Find two consecutive odd integers whose product is 23 more than their sum. Let x & x+2 be the 2 integers.
Step-by-step explanation:
The value of two consecutive odd positive integers are 5 and 6.
What are Integers?
A whole that can be positive , negative and zero is called integers.
Given that;
The product of two integers is 23 more that their sum.
Let two consecutive odd positive integers are x and x + 2.
Now, By the given condition we can formulate;
x (x + 2) = 23 + x + (x + 2)
x² + 2x = 23 + 2x + 2
x² + 2x = 25 + 2x
x² = 25
Take square root;
x = √25
x = ± 5
Since, Numbers are positive.
So, x = 5
And x + 1 = 5 + 1 = 6
Thus, The value of two consecutive odd positive integers are 5 and 6.

What is a Ratio mean?
Answer:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6∶8 and the ratio of oranges to the total amount of fruit is 8∶14.
Step-by-step explanation:

At a sale, coats were sold for $11 each. This price was 55% of a coat's original price. How much did a coat originally cost?
Answer:
The coat originally cost $20.
Step-by-step explanation:
The original cost is of x.
At a sale, coats were sold for $11 each. This price was 55% of a coat's original price.
This meas that:
[tex]0.55x = 11[/tex]
How much did a coat originally cost?
This is the solution for x for the equation above. So
[tex]x = \frac{11}{0.55} = 20[/tex]
The coat originally cost $20.
Answer:
20
Step-by-step explanation:
so when setting up you put 11/x=55/100 then cross multiply. then you should get 55x=1,100 .
divide 1,100 by 55 then you should get your answer which is
x=20 :)

An athlete spends 75 minutes a day on a cardio workout and 60 minutes a day on strength workout. The athlete does the cardio workout 20 days in a month, and the strength workout 25 days in the month.
Which equation could be used to find n, the total number of minutes the athlete spends working out in the month?
20 × 75 + 25 × 60 = n
75 × 60 + 20 × 25 = n
20×75−25×60=n
75 + 60 × 25 + 25 = n

( 15n2 - 5n + 45 ) ÷ 5
I'm assuming we need to simplify this expression. (Tip when you are writing n squared, please write n^2, not n2.)
Since we can see that there is a 5 in each term inside the ( ), we simplify have to remove that if the whole thing is going to be divided by 5.
Answer:
(15n^2-5n+45)/5
=3n^2-n+9
Answer:
3n^2-n+9
Step-by-step explanation:
You would want to divide the 5 between each of the terms. 15n^2 ÷ 5 is 3n^2. 15 ÷ 5 is 3. The n^2 stays, so 3n^2. -5 ÷ 5 is -1. We don't have to worry about writing the -1. Rather, just write the -n, it is the same as writing -1n. Lastly, 45 ÷ 5 is 9. You have to put the terms together in standard form. Standard form is just writing the numbers from greatest power to least power. The 3n^2 would come first since 2 is the greatest power. Next would be the -n, and lastly the 9. The 9 is the constant, which always comes last. A constant would be a number without a variable after it, like 2x is not a constant but just 2 is. Therefore, the answer is 3n^2-n+9.
